WATERVILLE, Maine — Fire officials have been unable to determine the cause of a blaze at a Main Street building on Friday because of extensive damage to the structure.

Waterville Fire Chief David LaFountain said Tuesday the state fire marshal’s office listed the cause as undetermined. No one was injured.

LaFountain said firefighters were called to 18 Main St. at 4 p.m. Friday. The building housed a tattoo parlor on the first floor, an unoccupied apartment on the second floor and occupied apartments on the third and fourth floors.

The chief said the blaze started on the third floor, and the fire displaced three tenants living on the third and fourth floors and a first-floor business, Ink for Life.

Even though the business was heavily damaged by water, LaFountain said Ink for Life’s owners plan on reopening across the street in the old Levine’s clothing store building.

The top two floors were destroyed by the fire while the bottom two floors sustained heavy smoke and water damage, LaFountain said. Firefighters from Oakland, Waterville, Winslow and Fairfield battled the blaze.

LaFountain said the fire also caused minor damage to 16 Main St. and the back of the Silver Street Tavern at 2 Silver St.

The Silver Street Tavern is located on the corner of Silver and Main Streets.

Firefighters had things under control in about an hour and a half, the chief said.
